Don't want to step outside your stated survey area - - -

First, congratulations on attaining your majority.
Unless you've already spent a LOT of time with a good .22 handgun, this is your best bet for a "starter pistol."
You can learn more, cheaper, quicker, from a Ruger Standard or a Buckmark than with any of the other pistols you list. Get one of these (a used one is fine, really) and several boxes of assorted ammo and find what your pistol likes. Then buy ammo. Lots of ammo. And you know what? If you watch the sales at Wal Mart and other places, you can buy 500 rounds for the price of a box of .40 S&W ammo. Learn sight picture and trigger squeeze. Work with a coach and LISTEN to the coaching. Then you'll be in shape to get into the big bores.
If you want to make a game of it, just figure every 50 rounds of .22 you shoot saves you ten bucks. (Go ahead, put a pencil to it.) Stick that $10 in your stash place. By the time you get really good with the .22, you'll have enough money rat holed to trade in the .22 on the center fire of your choice, and you'll probably be really comfortable with a good quality handgun.
But I'll tell you a secret: You'll probably WANT to keep that .22 around . . . .
If you've been fortunate enough to have access to a .22 for some period of time, then the above doesn't necessarily apply.
As to choices of the CF guns, I agree with Dr. Rob: Some kind of 1911 with a .22 conversion unit, or a Browning HP.
Best wishes,
